No codes out of ECU. Solid ABS light and Brake Failure light. I still can't seem to find the pressure switch on any diagrams......hmmm...
I wish it was that easy! ABS system doesn't use engine vacuum pressure. If some one has a photo or clearer description of the pressure switch...
Yes. Both the ABS and Brake Failure lights come on simultaneously. The odd thing is that I have normal feeling brakes for 10 minutes. When I...
Is that pressure switch a swappable item? Or is it integrated into the pump?
I don't think it's that issue Wang because I bled new fluid through the whole system and still same problem. Any other ideas? I'm pulling my...
Having a very odd problem with my 89 328 and am close to losing my patience here. (car has ABS) When I start the car, I hear the booster pump...
Well, here's another update: (on an 1989 ABS car I believe there is no vacuum line to the booster. There is a separate booster pump.) When I...
Well, you're making me doubt it, but I'm pretty sure no "booster". Here is an update to my situation: Just let the car sit for 3 hours....

Can I bleed the rears with a power bleeder? I'm by myself here. First time bleeding on a Ferrari, but have done brakes many times on US cars.

So, what ended up being the issue?
I know this is an old thread...but what ended up being the problem? Thanks, Dan 89 328
I'm going to be selling my broken switch if you're interested....well it worked 2 weeks ago, so it must be fixable!
YOU GOT ME AT FIRST!!! Thanks again....glad it stayed in the fchat family. Still kills me the price I have to pay for a mirror switch! But,...
I won the auction. Looking forward to getting the switch! :-)
Did you ever figure out what this noise was? Thanks, Dan
I 100% agree. They have great customer service and know so much about these cars. Can't say enough good things. Dan
Can you still move the seat back and forth with the amp under there?
